Might be rough in a couple spots, with a low slung car like a GR Corolla on stock suspension be prepared to lose some plastic bits if you drive that in anger.

Tires are surface/condition dependent.  Stock class SCCA rallycross is limited to DOT tires, everyone pretty much universally runs snow tires.  Snow tires do ok, and can be faster than the "rally/rallycross" tires on hard packed surfaces.  Snows would probably do ok at that place as long as it's dry.  Studdable snow tires tend to be more durable.  My BMW has Mastercraft Glacier Trex.  Cobalt before was on General Altimax Arctics.

Beyond snow tires, its stuff like these guys sell.  NE Racing Tires.  The more mud/wet grass, the knobbier people go.  I haven't used any of them because of the limited size options, none fit my car right. The square edges on the shoulders are supposed to help with lateral grip while sliding.

If you're getting a second set of wheels, generally look at going as small of a diameter as you can fit over the brakes.

Snows have a glaring disadvantage in mud versus the knobbies.  If the dirt has a lot of clay and really gets packed, I've seen people experiment with 200TW semi-slick type tires.

Team O'Neil Rally School has a ton of videos on YouTube. You can start with this one. https://www.youtube.com/watch?v=WJ9B6wlGrPk.  Being good on the brakes is huge, scandi flick/pendulum turn are good to have in the toolbag.

Most people doing this stuff use or older cars. Even newer WRX/STis are seldom seen. I'd have to imagine the GR Corolla is similar to the STi, it has great bones for rally suff, but the stock suspension, wheels, and brakes are made for asphalt use and limit it for off pavement stuff.

If the place is pretty smooth it will likely be fine. Big harsh bumps are what damage stuff, small jumps can be fine.  Maybe get a ride along, then take a couple slow sighter laps and remember the bad spots.  This kind of stuff is infinitely more fun if you don't care about beating your car up.
